GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

Chevy Cruze gets first official tease

The Cruze has been a runaway success for Chevy. In fact the company has sold over 3.5 million of them since its introduction in 2008. And now the company is preparing to roll out the all-new second-generation model, previewed in the teaser image above. Set to be unveiled on June 24, the 2016 Cruze promises to be larger, yet lighter, that the model it replaces. It will pack new engines, safety features, and technologies – including the integration of Android Auto and Apple CarPlay. The new Cruze will be based on the same platform that underpins the new Volt and (among others) the new Opel Astra just introduced in Europe. It'll be a vital model for Chevy, which sells the Cruze in 115 countries around the world – chief among them China, Brazil, Canada, and these United States, where sales continue to rise despite the model's age and impending replacement. Look for the second-gen Cruze to hit dealers early next year, joining a revitalized Chevy lineup alongside such notables as the new Spark, Malibu, and Camaro. Cruze Control: Success Paves Way for Next Generation Chevrolet's best-selling global car surpasses 3.5 million sales 2015-06-03 DETROIT – Chevrolet Cruze, the brand's best-selling car around the world, has surpassed 3.5 million global sales, a milestone that comes as Chevrolet prepares to introduce the next-generation Cruze on June 24. "When we introduced the Cruze it replaced 15 other compact vehicles around the globe," said Alan Batey, president, General Motors North America and global Chevrolet brand chief. "By consolidating design, engineering and marketing efforts, we were able to produce an award-winning, value-driven sedan that won over customers around the world." Cruze is sold in 115 countries. The top global markets include China, the United States, Brazil and Canada. In the United States, Cruze total sales were 273,060 in 2014 – a 10 percent increase over 2013. It is also the segment's second-best seller to customers under 25 in the U.S. Importantly, Cruze brings new buyers to Chevrolet – 35 percent of all buyers are new to the brand. Additionally, of those who trade in a Cruze, 56 percent stay with Chevrolet and 23 percent trade in for another Cruze. "In every corner of the globe, Cruze has been successful at introducing new and younger customers to Chevrolet," said Batey.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.
